Fabric adds Synthorai as an OpenAI-compatible provider and fixes UTF-8 characters split across SSE chunks
Fabric v1.4.472, released 2026-08-29, adds Synthorai as an OpenAI-compatible provider (#2198), and v1.4.473 the same afternoon fixes multi-byte UTF-8 characters being corrupted when split across SSE chunks in the chat stream by decoding with persistent streaming state (#2203). The UTF-8 bug is the kind that only shows on non-ASCII output, so anyone running Fabric patterns over CJK or accented text was silently getting mangled results. Synthorai also appeared as a new provider in DeepChat v1.1.1 two days later.
